Treatment Pattern of Oral Anticoagulants (OAC) in Japan
Treatment Patterns of Newly Initiated Oral Anticoagulants on Japanese Non-valvular Atrial Fibrillation Patients Using a Japanese Claims Database
- To understand the treatment patterns of OACs and baseline patient characteristics of Japanese Non-Valvular Atrial Fibrillation (NVAF) patients
- To determine whether warfarin and dabigatran new user group can be balanced using propensity score matching using pre-specified baseline covariates.
- As an exploratory analysis, to assess mean duration of on-therapy follow-up time in database
